LED Tube Light Performance Advantage Is Very Obvious And The Cost Is Lower
LED Tube Light Light for the certification when the majority of institutions require single-ended power supply, but why do you want to single-ended power supply? Is it feasible to double-end? Double-ended power supply LED Tube Light Light, free end of the terminal may be charged, how to test this point?
Is the drive power supply isolated or non-isolated power supply? This is no limit. Relatively speaking, the use of isolated power supply lamp, the output power is safe low voltage, lamp shell and hand contact can be seen as a safe area, easier to pass safety inspection; drawback is the transformer volume, PF value and efficiency Will be affected. With non-isolated power supply, the power input and output are not isolated, the fixture is treated as a charged body, so the creepage distance and insulation requirements will be higher, including the lamp and the pin between the solder joints and The distance between the aluminum plate to be more than 5mm, lamp beads on both sides of the distance between the aluminum plate also requires more than 5mm.
As the performance of non-isolated power supply under the same conditions is very obvious and the cost is lower, if you can meet the insulation requirements and through the pressure and other tests, the market is more competitive. However, LED fluorescent tube performance and safety seems to be uncoordinated a pair of enemies, when the fish and bear's paw can not have both, although the production enterprises will therefore increase the cost of personal views is preferred safety regulations.
Market controversy LED fluorescent power drive has a non-isolated and isolated two non-isolated advantages of low cost and high efficiency. On the LED light failure, the temperature is small but the requirements of the lamp structure design insulation is reasonable over UL, TUV, CE, PSE. There are five non-isolated power supply UL. Such as the high cost of isolated power supply, the market competitiveness is not strong, heat affect the LED life, at least 20% shorter life. As the components than non-isolated, the probability of failure rate is relatively high, there are many lower than the non-isolation generally 78-82%, non-isolation efficiency of 87-95%. In view of this, non-isolation will become the future market share of absolute advantage.
1 environment-friendly lamps
Traditional fluorescent tubes contain a lot of mercury vapor, if broken mercury vapor will evaporate into the atmosphere, causing pollution. But the LED lamp is not using mercury, and LED products do not contain lead and other harmful substances, the shell can also be recycled, the environment does not destroy the role. LED lamp is recognized as the twenty-first century green lighting.
2 on the file, the color of clothing without damage
Less heat phenomenon Traditional lamps are tungsten wire light, will produce a lot of heat, and LED lighting efficiency has reached 140LM / W, high light conversion rate, the product surface temperature below 60 ℃, does not produce UV, the file, clothing also Does not produce fading phenomenon.
3 no noise
LED lighting will not produce noise, for the use of sophisticated electronic equipment for the best choice. Suitable for the library, office and the like.
4 protect your eyes
Traditional fluorescent use of alternating current, so every second will produce 100-120 times the strobe. LED lamp using LED constant current work, is the direct conversion of alternating current DC, effectively reduce the LED light failure, fast start, no flicker, protect the eyes.
5 no mosquito trouble
LED Tube Light Light does not produce ultraviolet light, infrared light and other radiation, mercury and other harmful substances, less heat. So not like the traditional lighting, there are many mosquitoes around the light source. The room will become more clean and clean.
